Pros
Join if: (a) if you are in you mid-career and you really don't care as long as you get your paycheck. (b) if you have a false opinion that you are smart but you really are mediocore compared to the general population in terms of the technical talent. You'll fit right in. (c) if you struggled through your engineering courses (and you just couldn't get them) and you just can't wait to start a job "somewhere". And you believe that once you are in you'll have the opportunity to explore your true passions by doing different things. (d) If you don't believe in work-life balance and you also don't believe in work.
Cons
Don't join if: (a) you are young and have lot of energy to take on challenging technial work (b) you enjoy good pay (c) you have the courage to work hard and differentiate yourself from your peers and you enjoy being recognized for your hard work (by money/bonuses/promotion) and not be empty words (d) you hate office politics (e) you don't believe in groupism
